CABLE RAILWAY.

SPECIFICATION forming part of Letters Patent No. 332,934, dated December22, 1885.

Application filed July 23, 1884. Renewed August 5, 1885. Serial No.173,657. (No model.)

To all whom it may concern:

Be it known that I, DANIEL J. MILLER, a citizen of the United States,residing at New York, in the county and State of New York, have inventedcertain new and useful Improvements in Cable Railways, of which thefollowing is a specilication.

My invention relates in part to a mode of supporting paired travelingcables Within the tunnel of a cable railway, and means for placingeither or both of the said cables into or out of operative position atwill, and, further,t.o mechanism by which the grip is made to deflectthe carrying-sheaves by vertical pressure, so as to move them out of itsown wayin passing and permitthem to fall behind it in position to againreceive the cable.

In the accompanying drawings, Figure I is a plan of a short section oftrack and slot rails,with road-grating between then1,containing slotsand operating-levers for setting the carrying-sheaves in either advancedor retracted position, as hereinafter described. Fig. II is a verticaltransverse section of the track and slot rails and grating, and anelevation of the carrying-sheaves and the mechanism for operating thesame. Fig. III is a plan or top view of one ofthe carrying-sheaves andits tilting frame. Fig. IV is a side elevation of the same, showing thecable and the lower portion of the grip with its jaws open in readinessto receive the cable.

-1 1 represent thetrack-rails, constructed with flanges by which theyare secured to the tunnel-yoke 2. The slot-rails are shown at 3 3,securely fastened to the yoke and braced by tie-rods 4 4, extendingthrough the risers of the yoke, as I have described in my applicationtiled on the 23d day of July, 1884, Serial N o. 138,594.

Between the track-rails 1 and slot-rails 3 are road-gratings 5, slottedfor the reception of flanged stopblocks 6,which fill the said slots inwidth and in lengthwith the exception of the space occupied by levers 7,the upper ends of which are about flush with the roadway, and when thestop-blocks 6 are removed may be placed at either end of theirrespective slots and there secured by replacing the stopblocks 6,inorder to set the tilting sheaves 8 8", by which the cable is carried orelevated, be-

neath the grip-slot 3 3 or otherwise, accordingly as it is desired toplace the cable in or out of the reach of the grip.

In Fig. II the sheave 8 is shown in working position and the shea-ve 8ain retracted position, dotted lines indicating the position occupied bythe sheave 8L when in working position. It will thus be seen that thecarryingsheaves may either or both be advanced or retracted laterally asrequired, so that paired cables can be used either optionally or bothtogether.

The bearings 9 of the carryingsheaves 8 8 are in tilting frames10,1nounted on trunnions 11 and connected, by arms 12 and links 13, withthe levers 7, by which the frames l() are tilted in either direction.'The tendency of the carrying sheaves, especially under the strain of thecable, is to gravitate to the advanced or working position shown by thesheave 8.

The connection between the arms 12 and links 13 is by a pin and slot,14. permitting the carrying-sheave and its tilting frame when in workingposition to be deliected without moving the lever 7, and to return bygravity and the strain of the cable to operative position when released.This deflection of the carrying sheaves is produced by vertical pressurefrom the grip or other attachmentto the car upon a rail, 15, (shown insection in Fig. Il and in side elevation in Fig. IV,) and connected byrigid links or rods 16 with the outer ends of levers 17, fulcrumed at18, and connected at their inner ends by links or chains 19 with theadjacent ends of tilting bars 20, fixed to the respective tilting frames10. The rail 15 is formed, as shown in Fig. IV, with downwardly-inclinedends to receive the rollers 56. It is supported on standards 21, hingedto the bottom dange of the rail 15 and at 22 to the I-beam ofthetunnel-yoke 2. The standards 21 are forced over in the direction inwhich the grip is approaching by the horizontal pressure of the said`grip against the inclined ends of the rail 15, while the inclination ofthe said rail ends causes the depression of the entire rail and thethrust-links 16 by the vertical pressure of the grip. The standards 2lserve-as struts to support the weight of the rail 15 and its attachmentsuntil hori- IOO zontal or endwise pressure is applied to the sail rail,as explained. The grip is shown at 51 constructed with a fixed jaw, 52,and a moving jaw, 58, each made double to engage with twin cables. Thefixed lower jaw is provided with supporting-rollers 54, on which thecables run when the jaws are open and the car at rest, and withadjustable deiecting arms or spools 55, for ej ecting or excludingeither one 1o of the twin cables from the grip-jaws at the will of theoperator, as described in Letters Patent No. 281,256, granted to Chas.F. Findlay and myself the 17th of July, 1883. The said gripisfurthermore provided with rollers 56, project- 1 5 ing downward from itsextremities for applying pressure to the rails 15, to depress the sameand to tilt the frames 10, in order to deliect the carrying-sheaves 8 or8 out of the way' of the passing grip.

It is preferable to mount the depressingrollers 56 on the ends of thegrip, as here represented; but it is manifest that this part of theinvention may be carried into effect by another and special attachmentto the car for thc purpose.

In order to reduce the amount of pressure required to tilt the sheave,the oscillating parts are all balanced or nearly balanced upon thetrunnions ofthe tilting frame.

3o Having thus described my invention, the

' following is what I claim as new therein and desire to secure byLetters Patent: A

l. A swinging carrying-sheave for atraveling cable and an oscillating ortilting frame in which it is journaled, in combination with avertically-movable bar connected to said osciliating frame and aprojection from the car for depressing said bar, as explained.

2. The combination of the tilting frame, a

4o sheave mounted therein for carrying a traveling cable, and the leversoperating, substantially as set forth, to tilt the frame and deflect thecarrying-sheave by vertical pressure from the grip orother attachment tothe car.

3. A cable-carrying sheave mounted in a tilting frame operated by alever for holding -..the said sheave in either position to permit orprevent the engagement of the cable by the the tilting frame in which itis mounted, the levers, connecting-links, and stop-block to x theadjusting-lever, and consequently the tilting frame and sheave, ineither position in which they are placed. j

5. A carrying-sheave for a traveling cable, mounted in a tilting frameopeijated by connections to iix in its retracted position or permit itto fall into operative position at will and capable of automaticdeflection while in operative position, substantially as and for thepurposes set forth.

6. The combination of the carrying-sheave, the tilting frame in which itis mounted, the levers and connections for controlling the position ofthe sheave relatively to the grip and slot, and thc slot-and-pinconnection between the operating-levers, permitting free movement to thetilting frame when the sheave is tipped to bring the cable within reachof the grip.

7 The combination, with a pair of sheaves for supporting twin cables andindependentlyoscillating frames in which they are respectivelyjournaled, as described, of a tilting device common to both, wherebyeither may be brought into active position at the will of the operator,and a projection from the car for engaging with said tilting device,substantially as set forth.

8. The combination of one or more carrying-sheaves for traveling cables,the tilting frame or frames in which they are mounted, the tiltinglevers and links, the verticallymoving frame, and the grip provided withrollers for tilting the frame andcarryingsheaves by vertical pressure,as hereinset forth.

9. In combination with a sheave for supporting a traveling cable, anoscillating or tilting frame in which said sheave is journaled, havingtrunnions whose axis passes through or near the center of gravity of theoscillating parts, as and for the purpose set forth.
